| description | Levofloxacin is an emerging contaminant that threatens the aquatic organisms and human health. Bi2WO6-based heterojunction materials exhibit positive photocatalytic degradation activity under visible light with highly stable hierarchical nanostructures for levofloxacin remediation. However, recycling in practical applications is challenging. Herein, a hybrid nanofibrous film comprising BiOBr nanoplates on a layered Bi2WO6 nanofiber was successfully synthesized using electrospinning, a solvothermal method, and successive ionic layer adsorption and reaction (SILAR). The size and quantity of BiOBr nanoplates grown on the fibers are controlled by adjusting the number of SILAR cycles. The BiOBr nanostructure obtained on the surface of the nanofibers controlled the photocatalytic activity of the sample. The resulting film exhibited superior degradation efficiency toward levofloxacin under visible-light irradiation due to its solid heterostructure, large specific surface area, high porosity, and enhanced visible-light response. The degradation efficiency of levofloxacin reached 95.25% after the system was exposed to visible light for 120 min, and five cyclic experiments demonstrated its excellent stability and reuesability. The Bi2WO6/BiOBr/polyacrylonitrile nanofibrous film provides a new strategy for developing high-tech equipment and other applications in environmental remediation. |
